Avoid extra GetObjectInfo call in DeleteObject API (#17599)

Optimize DeleteObject API to avoid extra 
GetObjectInfo call on the replicating side.

For receiving side, it is just a regular
DeleteObject call.

Bonus: Fix a corner case where version purged is 
absent on target (either due to replication not yet
complete or target version already deleted in a
one-way replication or when replication was disabled). 

In such cases, mark version purge complete.
